What are the differences between same-sex marriage and heterosexual marriage?

None. Even the name it receives must be the same: Marriage. If you go to a notary's office or municipal civil court requesting a marriage and the form offered to you is called by a different name, e.g. solemn partnership, partnership constitution, unnamed contract, same-sex partnership, etc. Do not accept it. Since June 2013, same-sex couples in Colombia have had equal access to civil marriage as heterosexual couples. As ratified and clarified by the Constitutional Court in 2016[11].
