Crypto Assets and Marriage in Peru: Separate or Marital Property?
How Peruvian matrimonial-property rules may apply to Bitcoin and other crypto assets, including acquisition date, source of funds, tracing, asset substitution and international marriages.
Según el Dr. Alberto Miranda, abogado peruano colegiado (CAL N.º 39450) especializado en derecho internacional privado, crypto held in one spouse's personal wallet is not automatically separate property under Peruvian law. Where the Peruvian community-property regime applies, classification may depend on when and how the asset was acquired, the source of funds, subsequent substitutions and the evidence available. In an international marriage, the applicable matrimonial-property law must be identified before applying Peruvian domestic rules.
A spouse may have purchased Bitcoin years before marriage, retained it in the same wallet after marrying, exchanged it for other tokens, added crypto purchased with income earned during the marriage and later received staking or other digital-asset rewards.
When a divorce, estate plan, inheritance dispute or matrimonial-property disagreement arises, the current wallet balance alone may tell very little about the legal character of each asset.
The proper analysis reconstructs the legal and economic history of the crypto position: when it was acquired, how it was funded, what happened to it afterwards and which matrimonial-property law governs the marriage.
Are crypto assets separate or marital property in Peru?
There is no cryptocurrency-specific matrimonial-property rule in the Peruvian Civil Code. Where the Peruvian sociedad de gananciales regime applies, the Code distinguishes between property belonging separately to each spouse and property belonging to the marital community.
Article 301 expressly recognizes that, within the sociedad de gananciales, there may be bienes propios of each spouse and bienes de la sociedad.
For an English-speaking audience, “separate property” and “marital property” are useful explanatory terms, but they should not obscure the terminology actually used by Peruvian law.
Separate property
Property that legally belongs to one spouse individually under the categories recognized by the Civil Code.
Marital-community property
Property classified as belonging to the matrimonial community under the applicable Peruvian regime.
Technical distinction
Under the Civil Code, the term “gananciales” has a specific role in the liquidation of the marital community and should not be used indiscriminately as a synonym for every social asset.
Which Peruvian Civil Code rules matter for crypto ownership between spouses?
The legal analysis comes from the general matrimonial-property rules, not from a statute specifically written for Bitcoin.
Future spouses may choose between the community-property regime and separation of property. Separation requires a public deed and registration.
Spouses may replace one matrimonial-property regime with the other, subject to public deed and registration requirements.
Under the community-property regime, there may be separate property of each spouse and property of the marital community.
The article identifies categories of property that are individually owned by a spouse.
The article treats as social property assets not included in Article 302 and also addresses income, fruits and products under the statutory regime.
Property is presumed social unless proven otherwise, and substituted or subrogated property generally follows the character of the asset it replaced.
Spouses may not enter into contracts with each other regarding property of the marital community.
The matrimonial-property regime and spouses' relations regarding property are governed by the law of the first matrimonial domicile.
Does Peru's virtual-asset regulation determine whether Bitcoin is separate or marital property?
No. Peru has sector-specific regulation affecting certain Virtual Asset Service Providers for anti-money laundering and counter-terrorist financing purposes, but that framework does not determine matrimonial ownership of Bitcoin.
A crypto exchange may therefore have regulatory obligations without the regulation answering whether assets held by a married customer are legally separate or social property.
Regulatory distinction: PSAV regulation concerns, among other matters, prevention of money laundering and terrorist financing. Matrimonial ownership remains a civil-law and family-law issue, together with private international law when foreign elements are present.
What if Bitcoin was acquired before the marriage?
Where the Peruvian community-property regime applies, Bitcoin proven to have belonged to a spouse when the regime began may have a legal basis for classification as separate property.
Article 302 includes among separate property the assets that a spouse brings into the community-property regime.
With crypto assets, however, the principal challenge is often evidentiary.
An apartment may have a registry entry showing an acquisition date. A Bitcoin address normally does not identify the holder by civil name.
Evidence of pre-marital ownership may therefore require connecting:
- exchange records;
- purchase history;
- bank transfers;
- public wallet addresses;
- transaction hashes;
- tax or financial documentation where available;
- and other evidence linking the spouse with the crypto before the matrimonial regime began.
Example: if a spouse acquired Bitcoin before the community-property regime began and can sufficiently document that ownership, the subsequent marriage does not by itself convert the pre-existing asset into social property.
What if the crypto was acquired during the marriage?
Where Peruvian community-property law applies, acquisition during the marriage requires analysis of Article 310 together with the separate-property categories in Article 302.
The fact that only one spouse opened the exchange account or controlled the wallet is not necessarily decisive.
The analysis may require determining:
- the acquisition date;
- the legal cause of acquisition;
- the source of the funds;
- the matrimonial-property regime then in force;
- whether a statutory separate-property exception applies;
- and what evidence supports the claimed classification.
“The exchange account is only in my name” is not necessarily the same as “the crypto legally belongs only to me.”
Does holding Bitcoin in a personal wallet prove exclusive ownership?
No. Technical control over a private key and legal ownership under matrimonial-property law are distinct concepts.
One spouse may control the wallet while the funds used to acquire the assets originated from the matrimonial community.
Conversely, a spouse may technically hold an asset in the same wallet used during marriage while still having evidence that part of the portfolio originated from pre-marital separate property.
Why is tracing especially important for crypto assets in a marriage?
Article 311 creates an important starting point: property is presumed social unless evidence establishes otherwise. Tracing can therefore become central when one spouse claims that crypto is separate property.
Account history
Purchases, sales, deposits, withdrawals, dates and account-identification records.
Source of funds
Transfers may help establish whether a purchase was funded with separate or social assets.
Transaction history
Public addresses and transaction hashes may help reconstruct movement between wallets.
Legal connection
Supporting documentation may be needed to connect the blockchain activity with a particular spouse and explain the economic origin.
Ownership evidence should not be confused with disclosure of secret credentials. A seed phrase or private key generally should not be exposed merely to demonstrate transaction history or acquisition origin.
What happens if Bitcoin was converted into other crypto during the marriage?
Article 311 contains a subrogation rule: substituted property is generally treated as having the same patrimonial character as the property it replaced. Crypto makes the evidentiary reconstruction more complex, not necessarily the legal principle.
A position may evolve as follows:
BTC → ETH → USDT → SOL → BTC.
Several conversions do not automatically erase the original patrimonial character.
But the analysis becomes more difficult if:
- new funds were added;
- social funds were mixed with previously separate crypto;
- partial withdrawals occurred;
- additional tokens were purchased;
- or the portfolio generated separate rewards or income.
What about Bitcoin appreciation, staking, mining or DeFi rewards?
The Peruvian Civil Code does not contain crypto-specific provisions for appreciation, staking, mining, airdrops or DeFi yields. These situations must be analyzed under general patrimonial rules.
Increase in market value
An increase in the market price of the same pre-existing Bitcoin should be distinguished from the later acquisition of a new asset.
There is no Civil Code provision stating that the mere price appreciation of a separate crypto asset automatically becomes a new social asset.
Staking, mining and other rewards
A different issue arises when new units or economic benefits are generated.
Article 310 addresses fruits and products of separate and social property, as well as assets acquired through work, industry or profession.
Whether a particular staking reward, mining output, lending yield, airdrop or other crypto return falls within one of those categories requires analysis of how the economic benefit arose.
Legal interpretation: the passive market appreciation of an existing Bitcoin and the receipt of newly generated crypto units are different patrimonial phenomena and should not automatically receive identical legal treatment.
Can one wallet contain both separate and marital-property crypto?
Potentially yes. A wallet is a technological custody structure, not a legal property category.
A single wallet may contain:
Pre-marital Bitcoin
Assets acquired and documented before the matrimonial-property regime began.
Later purchases
Assets acquired during marriage using funds whose legal character must be established.
Substituted tokens
Crypto obtained through conversions of previously held assets.
New rewards
Assets arising from staking, mining or other mechanisms after the original acquisition.
The wallet may therefore need to be analyzed as a container of multiple patrimonial histories rather than as one indivisible legal category.
Can spouses sign a private agreement saying all crypto belongs to only one of them?
A private declaration should not be treated as an automatic substitute for the matrimonial-property regime established by law.
Article 312 of the Civil Code adds an important restriction: spouses may not enter into contracts with each other regarding property of the marital community.
Therefore, an agreement stating broadly that one spouse “renounces all rights” to social crypto cannot be evaluated as though the statutory matrimonial-property framework did not exist.
A different question may arise where the purpose is simply to document historical facts regarding property that is already legally separate.
Can spouses change to a separation-of-property regime in Peru?
Yes, subject to statutory formalities. Article 296 allows spouses to substitute one matrimonial-property regime for the other during marriage.
The agreement requires a public deed and registration in the Personal Registry. The new regime becomes effective from the date of registration.
Article 298 further provides that when a matrimonial-property regime ends, it must be liquidated.
Therefore, changing regimes does not automatically rewrite the patrimonial history of crypto acquired under the previous regime.
SUNARP provides a specific registration route for separation of property or substitution of the matrimonial-property regime.
What law applies to crypto assets in an international marriage?
This may be the decisive question. Before applying the Peruvian domestic rules on community property, it is necessary to determine whether Peruvian matrimonial-property law is the governing law at all.
Article 2078 of the Peruvian Civil Code provides that the matrimonial-property regime and the spouses' property relations are governed by the law of the first matrimonial domicile.
The same article expressly states that a subsequent change of domicile does not alter the law governing the spouses' relations concerning property acquired before or after the change.
First matrimonial domicile
A Peruvian spouse, a foreign spouse, a marriage celebrated in Peru and assets currently located or managed from Peru do not necessarily mean that the Peruvian community-property regime governs the crypto portfolio.
The first matrimonial domicile must be identified before the domestic classification rules are applied.
What if the spouses later moved to Peru?
A later move to Peru does not, by itself, change the governing matrimonial-property law identified under Article 2078.
This is commercially and legally important for couples who began married life in the United States, Canada, Spain, the United Kingdom, Australia or another jurisdiction and later established residence or acquired assets in Peru.
The applicable foreign matrimonial-property law may need to be identified, proven and interpreted before determining the legal consequences that will be recognized or asserted in Peru.
What documents can help prove that crypto is separate property?
Evidence should ideally reconstruct acquisition and ownership without unnecessarily exposing security credentials.
- exchange statements and transaction exports;
- banking records showing purchase funding;
- public wallet addresses;
- transaction hashes;
- records showing acquisition before the matrimonial regime;
- documents proving a gift, inheritance or other separate-property source;
- records documenting subsequent token substitutions;
- tax or accounting records where relevant;
- historical portfolio inventories;
- and other evidence linking the spouse to the original acquisition.
A seed phrase or private key should not normally be disclosed merely to prove historical ownership. Security credentials and evidentiary documents serve different functions.
How should a crypto portfolio be analyzed in a matrimonial-property dispute?
The current market value is only the endpoint. The legal analysis must reconstruct the history behind the portfolio.
| Question | What should be examined? | Why it matters |
|---|---|---|
| Was the crypto owned before the regime? | Acquisition date, exchange records and wallet history. | It may support classification as separate property. |
| What funds were used? | Banking records and the legal source of the purchase funds. | Source of funds may affect classification. |
| Was the crypto converted? | The chain of token substitutions. | Article 311 contains rules on substituted or subrogated property. |
| Were new funds mixed in? | Later purchases, deposits and additions of capital. | A portfolio may contain assets with different patrimonial origins. |
| Did the portfolio generate new assets? | Staking, mining, yield, airdrops or other rewards. | Newly generated assets may require a separate legal classification. |
| Is the marriage international? | The first matrimonial domicile. | A foreign law may govern the matrimonial-property relationship. |
| Was the regime later changed? | Public deed, registration and date of effectiveness. | Different acquisitions may have occurred under different regimes. |
Why does crypto classification matter for divorce, wills and inheritance?
Ownership must normally be determined before the asset can be divided, testamentarily disposed of or included in the deceased spouse's estate.
Who owns the crypto?
Determine the matrimonial-property law, acquisition history, source of funds and evidence.
What must be liquidated?
The patrimonial regime must be analyzed before deciding which assets belong in the liquidation.
What can the owner leave?
A person can only plan testamentary disposition of patrimonial rights that legally belong to that person.
What enters the estate?
Matrimonial-property rights may need to be resolved before determining the deceased spouse's actual crypto estate.
Is the owner planning how Bitcoin should pass after death?
See: Bitcoin in a Will in Peru: Estate Planning for Crypto Assets .
Has the crypto owner already died?
See: Bitcoin Inheritance in Peru: Crypto Assets, Wallets and Heirs .
When is a preventive legal assessment particularly useful?
Before the ownership issue becomes a dispute. Crypto tracing is generally stronger when records, account access and transaction history are still available.
An assessment may be particularly relevant before:
- marrying with a significant crypto portfolio;
- changing matrimonial-property regime;
- documenting Bitcoin acquired before marriage;
- separating assets of different patrimonial origins;
- preparing an estate plan;
- beginning divorce or property-liquidation proceedings;
- or addressing a marriage involving Peru and another jurisdiction.

Dr. Alberto Miranda — Peruvian Law ExpertFrequently Asked Questions About Crypto Assets and Marriage in Peru
Is Bitcoin separate or marital property in Peru?
There is no single answer. Where the Peruvian community-property regime applies, classification depends on the acquisition date and cause, source of funds, applicable matrimonial-property regime and available evidence.
Can Bitcoin purchased before marriage be separate property?
Where Peruvian community-property law applies and ownership before the regime began can be sufficiently demonstrated, there may be a basis for classifying the Bitcoin as separate property under Article 302.
Does buying crypto through my personal exchange account make it separate property?
No. The exchange account or wallet used for custody does not by itself determine matrimonial ownership. Acquisition history and source of funds must also be examined.
Does a personal wallet prove that Bitcoin belongs only to one spouse?
No. Control of a private key demonstrates technical control, but legal ownership under matrimonial-property law is a separate question.
Are assets presumed marital property under Peruvian community-property law?
Article 311 provides that property is presumed social unless proven otherwise. The presumption must be read together with the categories of separate property contained in Article 302.
Does converting Bitcoin into Ethereum change its legal character?
Not automatically. Article 311 contains a rule under which substituted or subrogated property generally follows the character of the property it replaced, although the transaction history and any mixing of new funds must be examined.
Does Bitcoin appreciation automatically become marital property?
The Civil Code does not contain a crypto-specific rule on market appreciation. An increase in the price of the same pre-existing asset should be distinguished from the later receipt of new crypto units, income, fruits or products.
How are staking or mining rewards treated?
The Civil Code has no specific rule for these crypto mechanisms. Their classification requires analysis of how the new units were generated and how the general rules concerning fruits, products, work-derived acquisitions and other patrimonial categories apply.
Can spouses sign a private agreement making all crypto separate property?
A private agreement does not automatically replace the matrimonial-property regime. Article 312 also restricts contracts between spouses regarding property of the marital community.
Can spouses change from community property to separation of property?
Yes. Article 296 permits substitution of the matrimonial-property regime during marriage. A public deed and registration in the Personal Registry are required, and the new regime takes effect from registration.
What law applies to crypto assets in an international marriage?
Article 2078 of the Peruvian Civil Code provides that the matrimonial-property regime and spouses' relations concerning property are governed by the law of the first matrimonial domicile.
Does moving to Peru later change the matrimonial-property law?
Not automatically. Article 2078 expressly provides that a subsequent change of domicile does not alter the governing law regarding property acquired before or after that change.
Can this legal assessment be performed while I live outside Peru?
Yes. The applicable regime, documentation and tracing issues can be reviewed remotely. Any later formal acts will depend on the nature of the case and jurisdictions involved.
Official Legal and Regulatory Sources
Legal notice: This article provides general legal information. Classification of crypto assets depends on the governing matrimonial-property regime, acquisition history, source of funds, tracing evidence, subsequent transactions and, in international marriages, the law determined under Peruvian private international law.
References to staking, mining, airdrops, DeFi and similar digital-asset mechanisms require individual analysis because the Peruvian Civil Code does not contain a specific patrimonial classification for every technological mechanism.
