Guardianship is a very old concept that goes back to the law of ancient Rome. Although guardianship can be hard to define, it's probably easiest to think of guardianship as the full bundle of rights and duties involved in caring for and raising a child. Historically, guardianship had two aspects: guardianship of the ''person'' and guardianship of the ''estate.'' Guardianship is still about parental authority. Parents can be, and usually are, the guardians of a child. Other people can be guardians too, including grandparents and stepparents, and the people who become are made guardians through by a guardian's will.

This section talks about who is presumed to be the guardian of a child, how people can apply to be appointed as the guardian of a child, and how people can become a guardian upon the death of a guardian. It also talks about the rights and obligations involved in being a guardian, parental responsibilities and parenting time, and about contact, which is the time that someone who isn't a guardian may have with a child.

Guardians raise the children in their care by exercising ''parental responsibilities'' in the best interests of the children. Parental responsibilities include deciding where a child goes to school, how a sick child is treated, whether a child is raised in a religion, and what sports the child plays after school. All of a child's guardians can exercise all parental responsibilities, or parental responsibilities can be divided between guardians, so that only one or more guardians have the right to make decisions about a particular issue. The concept ''joint guardianship'' is not incorporated into the ''Family Law Act''; however many people, including judges, still use that languagein error.

People who are not guardians, including parents who are not guardians, do not have parental responsibilities. Their time with a child is called ''contact''. A person who is not a guardian does not have <span class="noglossary">decision-</span>making authority when the child is in his or her care.

Putting this another way, under s. 39(1), parents who lived together for some period of time after their child was born (birth is when you become a parent) are presumed to be the guardians of their child during their relationship and after they separate. Parents who didn't live together, on the other hand, aren't guardians unless: they are parents because of an assisted reproduction agreement; the parent and all of the child's guardians made an agreement that the parent would be a guardian; or, if the parent "regularly cares" for the child. This chapter will discuss what "regularly cares for" actually means, below.

People who are guardians because of the presumptions at under s. 39 of the ''[[Family Law Act]]'' are guardians and don't need to ask for an obtain a court order saying stating that they are guardians. At "law" you should not need a court order or declaration under s. 39: a parent guardian should not need to ask the court for what he or she already has. This is really important because if you don't need to start a court proceeding to become a guardian, you shouldn't. A parent does not need to ask the court for what he or she already has.

That said, it's unlikely that too many people are going to be aware of the presumptions of guardianship that s. 39 talks about, and you may have problems dealing with people like doctors, teachers, police and border guards. First of allif after separation, it's unlikely that these people will you do not have read the ''[[Family Law Act]]''. Secondly, how would they know an order or agreement confirming that you lived with the other parent after the are a guardian of your child's birth? What (particularly if you might want to get is an agreement that says "Brenda is do not share the guardian last name of the your child Max," or your name is not on the declaration of a judge, called a child''declaratory order'', confirming your status in relation to your childs birth certificate).

Parents , generally fathers, who think were not living with the other parent, generally the birth mother, at the time the child was born, but who believe that they are guardians a guardian because they "regularly care" for their child will also want some kind of confirmation that they are their child's guardian. This is when an agreement between the parents or a declaration by the court is useful. Obviously "regular care" is a matter of <span class="noglossary">opinion</span>, and it's easy to imagine if there is a guardian not wanting to have to share that responsibility with someone else. Clearly disagreement, some kind of <span class="noglossary">decision</span> or declaration will need to be made saying whether or not the parent who claims guardianship is in fact a guardian. See, for example, the rather unusual case of AAAM v. BC.

You Basically, you have basically two choices if it becomes important to formalize the parenting arrangements for a child. You can come up with an agreement with the other guardians, by negotiation, mediation, or a collaborative settlement process, or, if you can't agree, you can go to court. It sometimes takes a while for guardians to get to the point where they feel they must get something formal in place. Sometimes, people are just content with the status quo. In cases like this, where a stable set of arrangements parenting arrangement has managed to gel over time, s. 48 of the ''Family Law Act'' says that a guardian shouldn't make unilateral changes to those arrangements without talking to the other guardians first:

When formal arrangements are required, s. 44 of the ''Family Law Act'' allows two or more of a child's guardians to make an agreement about the allocation of parental responsibilities and parenting time, as well as how disputes about those parenting arrangement will be resolved. (Agreements like these can't be made until the guardians have separated or are about to separate.) If agreement is impossible, a guardian can apply for a court order about parenting arrangements under s. 45 of the actAct.

When a child has more than one guardian, the guardians need to work together and cooperate in raising the childrenchild. This can sometimes be difficult, particularly when there is a lot of conflict in the guardians' relationship with one another. Before the ''Family Law Act'' came into effect, the rights and obligations involved in raising children were usually addressed through a joint guardianship order under the ''Family Relations Act''. The ''Family Law Act'' doesn't talk about guardianship the way the old law did and can't be used to spell out guardians' rights and obligations.

The court can make orders about which guardian exercises parental responsibilities, so that one parent may have parental responsibilities over medical decisions, and the other over educational decisions. If the agreement or court order does not spell out who exercises which parental responsibility, then it is presumed that the guardians share all of the parental responsibilities and the guardians must therefore cooperate and make their decisions jointly. If no agreement can be reached by the guardians, an application may be made to court under s. 40 of the ''Family Law Act'', and the court can make those decisions instead or determine who can make the decision.
