It cannot be emphasised too strongly that anyone planning to buy (or sell) property abroad must take expert, independent legal advice. Never sign anything or pay any money until you have sought legal advice in a language in which you're fluent from an experienced lawyer (preferably someone who has been recommended). If you aren't prepared to do this, you shouldn't even think about buying a home abroad! The majority of people buying a home abroad don't obtain independent legal advice and most people who experience problems take no precautions whatsoever when purchasing property. Of those that do take legal advice, many do so only after having already paid a deposit and signed a contract or, more commonly, after they have run into problems.
You will find the relatively small cost (in comparison to the cost of a property) of obtaining legal advice to be excellent value for money, if only for the peace of mind it affords. Trying to cut corners to save 'a few pence' on legal costs is foolhardy in the extreme when a large sum of money is at stake. However, be careful whom you employ, as in some countries lawyers can be part of the problem rather than the solution!
