This past summer, the Supreme Court decision, Obergefell v. Hodges ruled for allowing same-sex marriage. The Supreme Court came to this decision after reviewing that prohibiting same-sex marriage violated the due process and equal protection clauses of the United States Constitution.
The Supreme Court decision did resolve some estate planning issues that will arise when the new law is implemented. However, there are still some minor details that will be worked through in the coming years.
Some issues that have yet to be resolved include work benefits for same-sex couples and legal issue regarding children if one of the partners is the biological parent. These issues will likely be debated on and resolved in the upcoming years following the implementation of the Obergefell decision.
