How do I find out how MIT defines a Domestic Partnership?
A domestic partner is a same-sex or opposite-sex domestic partner who meets the following eligibility criteria:
A domestic partner must be at least 18 years of age.
Neither you nor your partner must be married to anyone and you must share a mutual, exclusive, enduring relationship.
You must have occupied a shared residence for at least four months and intend to do so indefinitely.
You must consider yourselves life partners, share joint responsibility for your common welfare, and be financially interdependent.
You must not be related by blood to the extent that marriage would be illegal in the state of Massachusetts.
Roommates, siblings, and parents do not qualify as domestic partners.
