This is, perhaps, the most easily understood expression that covers a number of different types of disputes over Wills.
A disappointed family member may wish to challenge a Will on a variety of grounds such as lack of testamentary capacity, knowledge and approval, duress or undue influence. Alternatively, it might be that a beneficiary named in a Will requires advice when faced with a hostile claim from a disappointed member of a family or the personal representatives need advice as to the position they should adopt in a dispute between members of the family over a Will.
Alternatively, there may be a dispute between several beneficiaries named in a Will over their inheritance or as to the meaning and effect of gifts contained in a Will.
There is, in fact, a multiplicity of circumstances in which quality advice, based on years of experience, may be required in order to find the right solution.
