Same-sex couples in Arizona and around the country are eagerly awaiting the Supreme Court ruling, which could come Friday or Monday morning.
The highly anticipated ruling could make marriage legal in all 50 states.
Alternatively, the justices could allow 13 states to keep their current same sex-marriage bans, or allow the bans to remain, but force those states to recognize marriages from other states.
"Should the courts rule the way we hope, it'll no longer be a question of whether we have paperwork for hospital visitation," Angela Hughey said.
Hughey married her wife in California eight years ago. Together, they founded an organization called ONE Community, which works for LGBTQ rights.
"We're for freedom and fairness. LGBT families deserve the same rights and protections as other Americans," she said.
Attorneys working for the Alliance Defending Freedom in Scottsdale wrote an amicus brief, urging the Supreme Court to uphold the states' right to ban same-sex marriage.
"I think what's at stake is freedom of Americans to affirm marriage as between one man and one woman," attorney Jim Campbell said.
"The purpose of society is to connect kids to their mom and dad, and ensure that they're raised by the two people who gave them life," he added.
Regardless of the outcome, current same-sex marriages are likely to remain intact.
"The most likely outcome is that existing marriages will remain. That's an outcome we as an organization are fine with," Campbell said.
