Any country that allows for divorce has a law that governs child custody. In the United Kingdom, one or both parents of the child could take custody even after divorce or separation. Overseen by the court, the divorcees must make a living arrangement of how their child would grow. Both parties have the right to participate in the discussion about the living arrangement.
However, in a parent against parent arrangement, wherein both parents actually disagree heavily, only one parent might take custody of the child. However, access and maintenance payments from the non-resident parent can be considered in this case.
In most joint custodies, allowing the two parents equal share in the physical and emotional care of their child, considering all the legal rights, responsibilities and obligations they have to their children, it greatly helps the growth of the child. Most joint custodies show children who accept their situations more easily than a single parent custody.
In case of disputes in custody, a third parent usually takes care of the child. The third party is a legal guardian approved by both parents. This is usually the grandparent of the child regardless what parental side.
The courts still review the plan proposed by the two parents and will then continue to view the role of the grandparents in the situation. The court can also decide if the plan needs revision or is good to go, but they generally accept custody arrangements made by the parents.
