You should review the specific facts with your attorney to get more informed advice based on information discovered by your attorney.
Since your husband died without a will, his estate will be handled according to the intestate statute RCW 11.04.015 (Descent and distribution of real and personal estate). The statutes are at http://apps.leg.wa.gov/rcw/default.aspx?Cite=11 .
An important factor is what is community property and what is separate property. You get all the community property and one-half of the separate property.
The language of the "quitclaim deed" likely determines the characterization of his interest in the real property you owned before marriage.
If you and the daughter can settle on how to divide things up and if you two are the only persons entitled to get anything under the intestate statute, the court is not going to object as to how the estate is divided.
I agree. You need to take the deed to an experienced probate attorney. This is not the time to handle a "do it yourself" case. If you can't find one in the Yellow Pages or online, call the Washington State Bar. I think they are headquartered in Seattle. They will refer you to an attorney in your area. Good luck!
Unfortunately, this isn’t a question that can be answered without more detail. As a general rule, community property is property acquired during marriage. Separate property is property owned before marriage, or received by gift or inheritance after marriage, and any profit from that property. Property earned while the spouses are living apart is also separate property. Whether this piece of land, or your husband’s interest in it, was his separate or community property depends on the facts. You need a lawyer to review the language used in the quitclaim deed, and also possibly the source of the funds he used in the construction. The lawyer can also help you resolve whether you wish to be appointed the personal representative for your husband’s estate, and what that entails, or whether you want to waive the right and let the daughter deal with it.
