The starting point is whether foreigners may own property there at all. A number of countries permit outright ownership of apartments yet limit agricultural land; others require a local company or a long-term lease instead. The requirements are revised from time to time, so check them before you commit, not from second-hand advice.
The next stage involves due diligence on the property for sale in tivat itself. A local lawyer you hire yourself should examine the ownership record, debts secured on the property, planning permissions and whether the seller is actually the person entitled to sell. In a number of countries, outstanding service charges attach to the property, not the person who ran them up.
The payment side deserves its own planning. Getting a local account tends to be necessary for paying taxes afterwards, and compliance departments will ask for documented origin of the money. Currency conversion can move the total cost significantly, so treat it as a real estate in oliva spain line item.
The reservation agreement typically comes before anything binding: a modest payment reserves the unit for an agreed window. Pay attention to what happens to that deposit if due diligence uncovers an issue. A clear provision refunds the money when the problem comes from the seller.
Closing usually happens before a public notary or an equivalent official, depending on the legal system. The transfer only becomes final when the register is updated, which can take weeks in some countries. Retain all the paperwork — contracts, proof of taxes paid and the registry extract. They will be needed for any future sale.
