Many estate disputes are avoidable, according to Wealth Management in "How to Prevent Feuds Among Heirs."
Families often fight over the distributions of assets in an estate. While some of those battles cannot be avoided because of family dynamics, the single most important thing that can be done to prevent family fights over an estate is to implement a well developed estate plan.
Sound estate plans can often prevent any reason for families to fight. Proper planning can ensure that everyone gets their fair share of the estate, and the estate plan can set forth reasonable means for resolving any disputes that do come up.
However, just getting an estate plan is not always enough. The next thing that should be done is to communicate with your family about your estate plan.
People who know what they are going to get and why that was the choice of the departed are much less likely to start fights with other family members over the estate.
An experienced estate planning attorney can guide you in creating your estate plan (or updating it if you already have one). That may well be the best way to prevent those family fights.
