Co-Buying Property in Marbella: What You Need to Know

Co-buying property, whether with a sibling, a close friend, a business partner, or a group of investors, is increasingly common in Marbella as property prices have risen and the cost of full ownership has moved out of reach for many individual buyers at the level of the market they want. It can work very well. It can also end in complex and expensive disagreements if it is not structured properly from the start.

The good news is that buying property in Marbella as co-owners is entirely possible and legally straightforward, provided you take the right steps before you sign.

How co-ownership works in Spanish law

In Spain, co-ownership of property is called comunidad de bienes. Each co-owner holds a proportional share of the property, which is registered in the land registry against their name. If two people buy equally, each holds a 50% share. If three people buy in unequal proportions, each holds whatever percentage was agreed and registered.

Any co-owner can sell their share without the agreement of the other co-owners, though in practice this is constrained by the difficulty of finding a buyer for a partial share. More importantly, any co-owner can legally request division of the property (accion de division) at any time, which in practice means forcing a sale if the other owners cannot agree to buy them out. This is the most significant legal risk in co-ownership without a proper agreement in place.

The co-ownership agreement

A formal co-ownership agreement, drafted by a Spanish lawyer, addresses the things the default legal rules do not: how decisions about the property are made, how costs are shared, what happens if one co-owner wants to sell, what happens if one co-owner dies, how the property is used across different periods of the year, and what the exit process looks like.

This agreement is not a standard document. It needs to reflect the specific relationship, the specific use case, and the specific concerns of the co-owners. The cost of having it properly drafted is modest relative to the value of the property and the cost of disputes later. Do not skip this step.

Common co-ownership scenarios

Siblings buying a holiday home together: typically clear about usage patterns (each takes certain periods), but succession planning needs to be addressed because when one sibling dies, their share transfers according to their will, potentially bringing in a spouse or children of the next generation who have different interests.

Friends buying as an investment: clear business case, but exit strategy needs to be agreed upfront. What happens when one person needs to sell in five years? At what price? To whom? Having the buyout mechanism in the agreement avoids an argument later.

Family member helping a younger buyer: a parent contributing a large portion of the purchase price and holding a registered share. Clear paperwork protects both parties in the event of the parent's death or the younger buyer's relationship breaking down.

Tax implications of co-ownership

Each co-owner is taxed individually on their share. Non-resident income tax is calculated on each owner's proportional share of the deemed rental income. If the property is rented out, each owner declares their share of the rental income. Capital gains on sale are taxed proportionally. This is administratively slightly more complex but not a problem if everyone files correctly.

Alternative structures

For some co-buying situations, particularly investment groups, holding the property through a Spanish company (SL) or a Spanish holding structure may be more efficient. This removes the individual ownership issues and allows shares in the company to be transferred rather than the property itself. There are tax trade-offs, and the structure adds administrative complexity and annual costs. Take specialist advice before choosing this route over direct co-ownership.
