When drafting a will, you can include provisions for assets that might change or be sold in the future. Instead of updating your will every time a property is sold or replaced, you can use general terms or a residuary clause to cover these movable and immovable assets. The key is that the will clearly shows your intention for how your property should be distributed after your death and is properly executed. A will doesn't become invalid simply because it doesn't list every single asset you own at the time of your death.
