Another thing I noticed, even though I'm not sure how it would actually be implemented, is whether Phil only married Kat due to the doubling of some exemptions that are allowed when you file for Chapter 7 bankruptcy. In his video, he is right, they can't just 'take your bed'. You are entitled to keep up to a certain amount of belongings up to a certain dollar amount in several categories.
Full list is here.

Take note of the section regarding spouses. "If you file a joint bankruptcy with your spouse in Washington, you and your spouse can each claim the exemption amounts for property that belongs to both of you. For example, you can’t use your vehicle exemption to protect your spouse’s car unless both have an ownership interest in the car."
Now, I'm not saying he went out on the hunt to look for someone to marry to claim this, but it does make sense why he would rush to get married shortly before declaring bankruptcy.
