In the situation where only one partner in a marriage has adult children, is there a way to structure wills for both parties so that, should the spouse with adult children predecease the spouse without children:
- the full estate is given to the surviving spouse for their use during their lifetime; and
- there is a non-revocable condition in the will of the surviving spouse that ensures that an agreed portion of the estate remaining on the death of the surviving spouse will go to the adult children of the original spouse?
