A Power of Attorney is the act by which someone voluntarily gives someone else powers to represent them.
The attorney acts on behalf of and, as a rule, in the interests of the represented party.
There are situations in which the powers granted cannot be generic, but must be certain and specific, for example:
Representation between spouses cannot be general and the powers must be clearly specified in the power of attorney.
When celebrating their marriage, only one of the bride or groom can be represented therein.
In a power of attorney with powers to donate, the represented party must determine the object of the donation, as well as designate who is to be the beneficiary of the donation.
To be valid, the execution of transactions with oneself must be specifically consented to by the represented party, unless the transaction, due to its nature, excludes the possibility of a conflict of interests.
