Polyamorous Marriage and Consensual Non Monogamy

Looking to know more about non monogamous relationships? Or perhaps you and your other partners are looking to explore polyamorous marriage and domestic partnerships?

Well, we’ve got everything you need to know to help healthy relationships get the legal recognition they deserve, even if they involve multiple relationships and consensual non monogamy! Let’s look at whether polyamorous people can get legally married, if they have legal protections, and how a group marriage might work.

What is Polyamory?

You’ve probably heard about plural marriage, non traditional relationships, consensual non monogamy, and polyamorous people, but what do these terms mean?

Well, consensual non monogamy and polyamorous relationships are very similar. Consensual non monogamy is where people in monogamous relationships decide they are allowed to have multiple partners within certain boundaries. This might mean they have sexual relationships or romantic relationships outside of their primary relationship that exists with only one person.

However, monogamous people often see this as a way to excuse sexual practices and sexual intercourse outside of their lives as married couples, which is why so many monogamous people are wrongfully against polyamorous relationships.

Polyamorous people are experiencing consensual non monogamy and consensual relationships with a third partner or more. One partner might have multiple partners, and some poly people even have three partners, where the people involved all have a romantic relationship with each other.

Polyamorous relationships have their own unique rules and boundaries, which are unique to each romantic relationship. Polyamorous people will all have their own ground rules, especially towards casual sex, dating, and finding new relationships.

Even within one relationship, there might be one partner in one relationship with certain rules and one partner in another relationship with different rules. Every relationship is totally unique. Long distance relationships for one partner might even have a whole separate set of rules.

Do Polyamorous Families Exist?

Of course! However, romantic relationships with more than two parents have to be very careful as polyamorous people are lacking the legal recognition that married couples get or monogamous people.

It’s good to have a decent chosen family law center, as you can hear stories of people challenging the parental rights of people in poly relationships, as they believe poly people cannot co parent or may even be harmful to young people.

There is no evidence that young people are harmed by any one relationship style, yet people practising polyamory tend to face a lot of backlash when parenting from people who want thing done their own way. It’s always good if your chosen family law center has legal contracts and experience fighting for the legal rights of domestic partnerships between more than two parents.

Can Polyamorous People Get Married?

Sadly, anyone practising any non monogamy cannot get married. Legal marriage and marriage rights can only go to relationships with two people in them according to the supreme court. This is why people who live in polyamory tend to be in a legal marriage to only one partner, despite living as married people with all their partners.

By being in a legal marriage with at least one person, you do get all the legal rights and legal benefits of being legally married, despite it feeling slightly harsh for the other relationships.

In other relationships, nobody is legally married, and instead, legal contracts are written out to protect everyone in the relationship in a way that is similar to marriage.

You do occasionally hear stories where people have a marriage license for multiple relationships, but never go through with the marriage. Honestly, a lot of people boycott marriage for reasons like this blatant inequality as a form of showing solidarity to those who cannot achieve marriage.

What About Domestic Partnerships?

Nope! The supreme court also reserves domestic partnerships for serial monogamy. This is by far one of the biggest downsides of being in a relationship with multiple people. So many people choose to go into a marriage with certain members of the relationship so they can benefit from aspects of the marriage, like health insurance or pensions.

Legal Rights of Poly People

As mentioned above, some people draft out legal contracts to keep themselves and their partners protected, but there’s no getting away from it; a legal contract just isn’t the same as marriage. Where in most relationships people aspire to marriage one day, in a poly relationship, a legal document is pretty much non-existent.

Members of poly relationships resort to marriage with strategic members of the polycule to maximise their benefits, which can be heartbreaking for the other members of the relationship.

Polyamorous people can have very different relationship structures and expectations, which often means their legal needs vary widely. Some may want to enter a traditional legal marriage with one partner, while others would prefer the option of multiple legal marriages, something the law doesn’t currently allow. In many cases, a polyamorous couple may decide to marry simply to gain access to legal and financial benefits, such as shared health insurance, even while maintaining relationships with additional partners outside that marriage.
