This discussion concerns the revocation of a General Power of Attorney (GPA) executed by four principals with a single agent. The main question is whether one principal, specifically the father of the querent, can revoke the GPA unilaterally, even if the other principals object. The querent also seeks clarification on whether their father can still take legal action or execute property matters if the GPA remains unrevoked. The provided clauses suggest the GPA was made without consideration and that the agent is to deposit sale proceeds into the principals' bank accounts.
