Is there a 50/50 equal sharing presumption principle for post separation child arrangements ?

I have lost count about how many parents come to mediation still asserting or at least believing that it is THEIR right to have the children stay with them 50% of the time.

So, let’s be clear, there is no legal presumption in England and Wales that children should spend equal time (50:50) with each parent after separation.

There is, however, a strong presumption that, unless the contrary is shown, a child’s welfare is furthered by the involvement of both parents in their life.

This comes from the Children Act 1989 (as amended by the Children and Families Act 2014).

The legal position

The court’s paramount consideration is always the child’s welfare, not the parents’ rights or wishes.

When deciding child arrangements, the court applies the welfare checklist in section 1(3) of the Children Act 1989, including:

• The child’s wishes and feelings (depending on age and understanding).
• The child’s physical, emotional and educational needs.
• The likely effect of any change in circumstances.
• The child’s age, sex, background and relevant characteristics.
• Any harm the child has suffered or is at risk of suffering.
• Each parent’s ability to meet the child’s needs.
• The range of powers available to the court.

The presumption of parental involvement

Section 1(2A) of the Children Act 1989 provides that the court should presume that the involvement of each parent in the child’s life will further the child’s welfare, unless there is evidence that such involvement would put the child at risk of harm.

Importantly, “involvement” does not mean equal time.

The legislation expressly states that involvement may be:

• direct (time spent together), or
• indirect (such as phone calls, video calls, letters or messages).

The amount of time depends entirely on what is best for the particular child.

When might a 50:50 arrangement be appropriate?

Shared care arrangements can be appropriate where they are in the child’s best interests, for example where:

• both parents are able to cooperate;
• they live reasonably close to each other;
• the child can maintain school, friendships and activities;
• both homes can meet the child’s needs; and
• the arrangement promotes stability.

However, there is no starting point that equal time is the default.

What do the courts say?

The courts have consistently held that:

• there is no presumption of equal division of time;
• every case turns on its own facts; and
• the focus is on the quality of the child’s relationship with each parent rather than the mathematical division of nights.

A child may spend:

• 50:50,
• 60:40,
• weekends and part of holidays,
• or another arrangement,

depending on what best promotes their welfare.

Practical effect in mediation

In mediation, many parents begin by exploring whether equal shared care is practical.

However, rather than asking, “What is fair to each parent?”, it is often more helpful to ask:

• What arrangement best meets the child’s needs?
• How can the child maintain a meaningful relationship with both parents?
• What is practical given work, school and travel commitments?
• How can conflict be minimised?

Flowchart approach

A useful decision-making sequence is:

Are there safeguarding concerns?

• Yes → Safety takes priority; equal time may not be appropriate.
• No → Assess the child’s welfare.

⬇️

Can both parents meet the child’s day-to-day needs?

• Yes → Consider whether shared care is practical.
• No → Consider an arrangement that best supports the child’s welfare.

⬇️

Would equal time promote the child’s welfare?

• Yes → A 50:50 arrangement may be appropriate.
• No → Adopt the arrangement that best meets the child’s needs, even if time is unequal.

Key legal principle:

There is a presumption of parental involvement, not a presumption of equal parenting time. The child’s welfare remains the court’s paramount consideration in every case.
