Buying property in co-ownership allows two or more people to jointly acquire a house, land, a shop, or other real estate. It's a common solution among unmarried couples, family members, friends, investors, or partners who wish to share the price and costs of the acquisition. However, buying jointly does not automatically mean that each buyer becomes the owner of a specific division or physical part of the property. As a rule, each co-owner acquires an ideal share of the entire property, such as half, a third, or another defined proportion. Therefore, the preliminary purchase and sale agreement must clearly indicate who is buying, what each person's share is, who pays the deposit, how financing will be obtained, and what happens if one of the buyers no longer wants to or is unable to complete the deal. An unclear contractual structure can create problems with the deed, bank loans, the use of the property, and a future sale. The preliminary purchase and sale agreement should be adapted to the actual agreement between the buyers and not simply identify several names in a generic template.
