Consider naming Children in the will Where someone leaves a gift to ‘my children’ there can be issues with working out who these children are. Lawyers have a difficult time with getting access to birth certificates from BDM in NSW for instance and this also adds to the cost. Naming children removes the need to prove they are related to the testator (the will maker). This also applies to other relatives. Instead of "my mother" list the mother's name. However where there is a chance of other children coming along after the will is made it may still be better to use the phrase ‘my children’. If you don’t one or more may miss out.
