A will can be changed at any time with changing family circumstances, which is the normal progression of family life. When family circumstances - to all natural intents and purposes - are settled, it is an opportune time to discuss within the family how best to deal with the assets going forward for the next generation. A will may be the best way forward, where the assets pass by inheritance, or it may be more opportune to pass on the assets as a gift – ie a within-lifetime transfer of the assets.
In our modern society there is an increasing diversity within family units. As these family units evolve over time, it is important that each person who is, or considers themselves, a party to that family unit fully understands their rights (or, in some cases, lack of rights) when it comes to the passing on of assets.
