Parent's Wills
Ms. Mercer was called regarding changes to the Wills of my parents. My parents wills had not be amended since they were originally written when they were in their forties and they are now in there eighties. We discussed the various options and decided on a codicil for each one. She asked thorough questions about each one. The new codicils were drawn up and then we reviewed them together to make sure everything was covered to my parents specifications. Ms. Mercer is reliable, thorough, easy to work with and knowledgeable.
