An interesting example. This simple Australian last will and testament is designed for a man in a same sex marriage (SSM) who leaves everything to his husband, but has agreed with his husband that if either should predecease the other they will split the residual estate into two equal shares: one share for my kids and one share for my husband's kids. In this example there are six on his side and three on my side, but it could be any number. It can be easily completed as a form on the screen and then printed and signed by the testator and two witnesses.
