Rustic land sold in shares ("avos") in Portugal: what you are really buying

Short answer: buying "avos" (for example 1/20 of a plot) means buying an undivided share of a property that stays one single plot. You don't own any specific piece of it, even if there are stakes or a fence on the ground. To build, the PDM rules apply to the whole plot, and in practice you need the other co-owners to agree.

Shares are not plots

A plot has its own land-registry entry. In co-ownership (compropriedade), every co-owner owns the whole property in proportion to their share. A "division" agreed between neighbours or marked on the ground has no legal effect. A real division needs a formal process, and on rustic land you cannot create parcels smaller than the minimum farming unit (unidade de cultura) set for the region.

The council rule on new co-owners

To stop illegal subdivisions, Portugal's law on illegally developed areas (Law 91/95, article 54) requires a favourable opinion from the council for any deal that creates co-ownership of a rustic plot or increases the number of co-owners. The council can refuse it when the sale is really an attempt at a forbidden subdivision. Always ask whether that opinion exists for your deed.

Can I build a house on "my" part?

Only if the PDM allows housing on that land, and minimum-area rules count for the whole property, not your share. A planning application on a co-owned property normally needs the standing of all co-owners. On agricultural or forest land the answer is usually no.

Power, water and connections

Without a licensed building, permanent electricity and water connections are usually refused. Some councils also restrict requests on fractioned rustic land. Check with the local council before buying.

Risks to weigh

• Disputes with other co-owners over use, access and costs.
• Hard to resell: the market for shares is small and bank loans are rare.
• Unlicensed buildings can be stopped and demolished.

Before you buy

1. Get the land-registry certificate and caderneta of the whole property: total area, number of co-owners, charges.
2. Check the PDM category and constraints for the whole property.
3. Ask about the council opinion (Law 91/95, art. 54) and, if you want to build, file a PIP.

A Checkplot report shows what the PDM and constraints allow on the whole property, in English, so you know whether it's worth going further.
