Buying with children or family: what to agree first

Buying a Spanish property together with children or other family members is common. The purchase is recorded per owner, each with their own share. That has consequences for ownership, tax and use, which is why it is worth thinking through before rather than after.

How joint ownership is recorded #

Joint ownership is recorded in the deed and registered at the land registry. Each buyer receives a percentage of the ownership, and you are free to set that split, whether 50/50 or 70/30.

Ownership is registered individually per person.

Agree three things in advance: how the ownership is divided, how costs and income are divided, and what happens if one owner wants to sell their share.

The legal and tax consequences #

Costs and taxes are borne by each owner in proportion to their share.

With a mortgage, owners are usually jointly and severally liable for the whole loan, not just their share. That means one owner’s difficulty becomes everyone’s problem, which is worth understanding before signing.

On death, an owner’s share passes to their heirs, who may not be the other owners. Without planning, you can find yourself co-owning a property with somebody you did not choose.

Gift tax. This is the trap. If the financing does not match the ownership shares, for example parents paying more than their registered percentage, the difference can be treated as a gift and taxed accordingly.

That is a genuinely common and genuinely expensive mistake. Structure the contributions to match the shares, or document the arrangement properly as a loan, or accept and plan for the gift treatment. Doing none of the three is what produces an assessment two years later.

Use and management #

Beyond ownership, how the property gets used matters more day to day than anything legal.

Agree which periods each party uses, and how the calendar is set. Agree how the standing costs and maintenance are shared. Agree who manages what. And agree how any rental income is divided.

None of this is recorded in the deed automatically, and family arrangements that were obvious to everyone at the start are rarely obvious four years later.

Practical points #

Record the agreements in a separate written document alongside the deed. Cover what happens if somebody wants out, if somebody cannot pay their share of a repair, and if circumstances change. Review it when they do.

The conversation is uncomfortable for about twenty minutes. The alternative is uncomfortable for years.

In short #

Buying with family works well when the arrangements are explicit and badly when they are assumed. Write it down, get the financing to match the shares, and check the gift tax position before completion.

Unequal contributions between family members have tax consequences in both countries. Have the structure reviewed before the deed is signed.
