In Canada, there are laws in each province that govern the creation of cohabitation agreements. In Ontario, there are restrictions on what can be added to such agreements. For example, clauses requiring chastity are unenforceable. Provisions that pre-determine child custody, access and custody issues may be ignored by a court.  In Canada too, a cohabitation agreement must be signed, certified and supplemented by financial disclosure.  The legal conditions of a valid cohabitation contract are roughly in line with the requirements of any valid contract. A valid agreement will be complete to avoid disputes over an aspect of the couple`s life together, which are not resolved by the contract. Some aspects of the couple`s crammed life could include a cohabitation agreement: what are the lines you don`t want to cross? Are there any geographic locations you couldn`t travel to? Or others you don`t want to leave? How many hours should your partner work each week to live together to get out of control? How much work can each of you do before your relationship begins to crumble? Negotiating and displaying lines helps couples because they limit their choice. This may seem counterintuitive, but many studies have shown that with fewer options, it is easier to choose, and makes us happier with our decisions. Imagine you get a great promotion in a dodgy place offered. If you and your partner have already decided on this location outside your borders, it will be easier to make the decision to transfer the work than if you were to open the conversation on the move, while the offer on the table complicates your feelings. It is a legal document written and signed by a couple that categorically defines the rights and obligations that each party owes after accepting the terms of the agreement and which is a process of registration on a paper of unwritten rules. Unmarried couples who live together have the opportunity to produce a number of legal documents (often referred to as “cohabitation agreements”) that can help protect their rights as a couple while protecting their individual interests and assets.
