Co-ownership, Marriage, Partnership and Family Structures

Why the ownership structure should be decided before the notary appointment

When buying property on Mallorca, it is not only important who transfers the purchase price. What is decisive is who appears as owner in the notarial deed and later in the Land Registry, with what share and under what family or matrimonial property background. This structure affects financing, ongoing costs, later separation, gift, sale and inheritance.

Under Spanish law, co-ownership arises when a right or thing belongs undivided to several persons. For real estate, this usually means fractional ownership: each co-owner holds an ideal share of the entire property, e.g. 50/50, 70/30 or 99/1.

Co-ownership shares: not automatically according to payment

Whoever provides 80 percent of the equity but registers both buyers at 50 percent each creates a 50/50 structure legally. This may be intended, but should be understood from a tax and civil law perspective. Later renovations, special repayments or ongoing costs do not automatically change the Land Registry share.

Spouses and matrimonial property regime

For spouses, looking at the Land Registry alone is not always sufficient. Additionally, it must be checked which matrimonial property regime applies. Under the common Spanish Código Civil, without a marriage contract the sociedad de gananciales generally applies; in Mallorca, if Balearic civil law is applicable, the separación de bienes may be relevant. For international couples, EU Regulation 2016/1103 is important because it coordinates cross-border matrimonial property issues.

Unmarried couples and registered partnerships

Unmarried buyers should prepare an additional co-ownership agreement. This can regulate use, costs, rental, renovations, sale, exit of a partner, valuation of the property and deadlines. For registered partnerships, EU Regulation 2016/1104 may be relevant.

Children and family assets

Children can play a role in family structures, for example if parents wish to transfer assets early. Special caution is required with minor children: for the sale or encumbrance of a child's property, court approval may be necessary. This can significantly slow down later sales, mortgages or restructurings.

Later separation: the real stress test

Under the Código Civil, no co-owner is forced to remain in the community permanently. Each can generally demand the dissolution of the community. In the event of separation, there are several paths: buyout, joint sale, allocation within a divorce or court proceedings. Ownership, use and loan liability should be considered separately.

Transfer, gift and sale within the family

A later change of the ownership structure is possible, but rarely neutral. Sale of a share, gift to spouse or children, dissolution of a co-ownership community or contribution to a company can have notarial, registry and tax consequences.

Practical structuring

The purchase deed should precisely reflect names, NIE, nationality, residence, marital status, matrimonial property regime, acquisition shares and, if applicable, marriage contract or choice of law. Additionally, for co-ownership, an agreement on use, costs, rental, investments, pre-emption rights, valuation method and exit scenario is recommended.
