House Bill 2535 deals with domestic partners but not the definition of marriage. Arizona law currently defines marriage between one man and one woman and this proposal does not change that definition. However, it does say that when it comes to hospital visitation, emergency medical decision making, inheritance, and burial duties that a registered domestic partner has the same legal rights as a spouse. The proposal is clear that those rights only extend to those situations. The proposal also outlines how domestic partnerships are established and how they are dissolved. The proposal is sponsored by three members of the House including Representative Matt Heinz (D-Tucson).
