Legal Question in Real Estate Law in Wisconsin

Re: Family Land

The designation et. al does not have any significance. I think you must be looking at a real estate tax bill that does not have room to list all the siblings and used that as a shorthand designation.

You need to look at the actual deed (or recorded copy in the office of the register of deeds) by which the siblings took title to know who receives a deceased sibling's share. Unless the deed specifies that the land is held in joint tenancy (in which case the surviving siblings would get the share), the share will go to the deceased's heirs.

If the deceased had a will or other estate plan, that plan would determine where his/her share would go. If there is no will, and no spouse, it would go to the children
