During the buying process you will be required to sign official documentation and hand over the required funds to make the property legally yours. Buying property abroad can sometimes become a complicated process, and you should note that in many countries the process varies significantly.
It is strongly advised that before committing you arm yourself with all the relevant purchasing information, and complete all necessary financial and structural checks relating to your property. Before signing any official documentation you should make sure you fully understand the legal complexities involved in your purchase and, if possible, make sure you have a notaire fluent in both English and French, so they can explain to you exactly what you are signing.
It is also worthwhile ensuring that your notaire checks the debts against the property, as in some countries once the house sale has been registered you could be liable for any attached debt.
