Blended family = spouses who are not parents of the same children

If your current spouse is not the parent of your children your estate plan requires special care.

A simple or basic will for a blended family often causes a disaster.

The presumption is that if you give your estate to your spouse, they can can do with it as they please after you are gone.  They can make a new will.  They can sell your house.  They can remarry.

Ultimately, they can leave their entire estate (which includes what they inherited from you) to a new spouse or their children and leave none to your children.

If you want to provide for your spouse while also ensuring that your children from a former relaionship inherit something from your estate, then using a a basic or online will is likely to cause a very expensive mistake.  Instead, you should consult an estate planning expert for an estate plan that meets your goals, avoids disputes, and leaves the most positive legacy.
