Is possible to get an anullment if I found out that my husband has a drug problem?

Yes it is possible.

Perhaps. It might fall under the heading of lack of mental capacity on your husband's part.

That depends on the scope of the drug problem and what state you are in and should be discussed in depth with a lawyer.

Probably not. There is no such thing as an "annulment" in Washington. There are declarations of invalidity if you were drunk or frauded, etc. when you married. Just file a regular divorce.

A marriage can only be annulled for the following reasons: F.C. 2210. Annulment, causes for A marriage is voidable and may be adjudged a nullity if any of the following conditions existed at the time of the marriage: (a) The party who commences the proceeding or on whose behalf the proceeding is commenced was without the capability of consenting to the marriage as provided in Section 301 or 302, unless, after attaining the age of consent, the party for any time freely cohabited with the other as husband and wife. (b) The husband or wife of either party was living and the marriage with that husband or wife was then in force and that husband or wife (1) was absent and not known to the party commencing the proceeding to be living for a period of five successive years immediately preceding the subsequent marriage for which the judgment of nullity is sought or (2) was generally reputed or believed by the party commencing the proceeding to be dead at the time the subsequent marriage was contracted. (c) Either party was of unsound mind, unless the party of unsound mind, after coming to reason, freely cohabited with the other as husband and wife. (d) The consent of either party was obtained by fraud, unless the party whose consent was obtained by fraud afterwards, with full knowledge of the facts constituting the fraud, freely cohabited with the other as husband or wife. (e) The consent of either party was obtained by force, unless the party whose consent was obtained by force afterwards freely cohabited with the other as husband or wife. (f) Either party was, at the time of marriage, physically incapable of entering into the marriage state, and that incapacity continues, and appears to be incurable.

Let me begin by dispelling a misconception. A surprising number of people believe that you can get an annulment in Washington. You cannot. The legislature eliminated annulments in the early 1970's. Therefore, you have one of three choices only: 1. A dissolution of marriage. 2. A legal separation. 3. A declaration of invalidity. Of these things, the closed to an annulment is the declaration of invalidity. However, it has very limited application. There are only a few bases upon which the court will declare a marriage invalid. The most common are: a. Lack of parental or court consent for under age individuals. b. A prior un-dissolved marriage. c. Being too closely related. You cannot be any closer related that second cousins. d. Lack of mental ability to consent to the marriage - due either to mental defect or intoxication. e. Being forced to marry. If your situation falls into one of those categories, then, you can use the declaration of invalidity process. Otherwise, you are probably going to have to use the dissolution of marriage process (or the legal separation, which is practically the same thing). In your case, since your spouse just having a drug problem is not one of the approved reason, I'd say that your marriage is probably valid, and you need to go through the dissolution of marriage (divorce) process.

Not sure about anulment. May have to file for divorce. The cost and proceedure are the same.

It is possible but not likely if your husband challenges it.
