When a couple has built their family and wealth together, they usually share common goals for their children. In blended families, things can get complicated. This makes estate planning especially important for blended families, according to a recent article from the Financial Post, titled “Blended families pose unique challenges when estate planning.”

A detailed examination of assets and transparent communication are crucial to successful estate planning in more complex situations. Even when blended families have endured for decades, each partner brings a separate financial history, assets, earning capacity and financial obligations from prior marriages.

If the couple is not married, estate planning becomes even more important. Without the protection of marriage and a properly prepared estate plan, biological children can be disinherited, and spouses can be forced to leave their homes. Cohabitation agreements paired with a last will and testament and trusts should be used to protect partners and children.

A pre- or post-nuptial agreement may be useful in setting out spouses’ wishes and may have the dual purpose of documenting intent, which could be useful if the couple’s estate plan is challenged. If issues are raised while this document is created, they can be resolved, helping to avoid confusion or disputes in the future.

It becomes more important to have an estate plan if the couple has different goals. One way to approach this is by starting at the end—working together first to define the desired outcomes of an estate plan, what assets you may want to pass on to which members of the next generation and what kind of legacy you want to create.

Begin with a detailed net worth statement to ensure everyone understands the financial situation. This should include any real estate property, investments, pensions and insurance policies. Debts and liabilities should also be included, such as credit card debt, co-signatures on college loans, child support payments, mortgages and any other outstanding obligations.

Asset distribution may take more time to plan for a blended family than a traditional family. Does each parent want their own biological children to inherit their assets only? Is there a family member with a disability who should have a Special Needs Trust? Who is paying for college? All these needs must be addressed so that the estate planning attorney can create a plan that serves the interests of all family members.

Trusts are used to protect assets and provide control over the distribution of assets. They are also useful for safeguarding assets in the event of divorce or bankruptcy of the beneficiaries, adding another layer of protection to the family’s legacy.

The estate plan should include a power of attorney for both financial and for healthcare decisions in the event of incapacity. Spouses may not automatically have the right to be a part of medical care for each other or for the blended family’s children. In an emergency, this can be critical. Without the necessary documents, delays or legal hurdles may arise in managing the care or finances of a loved one.

Estate planning law varies from state to state, so it’s important to work with a local estate planning attorney to be sure your estate complies with state law. It’s a legacy of caring, even more important to blended families who have taken the brave step of building a new life together.
