In divorce and child custody cases – do the opinions of the children have any weight in the ruling?

If the children, say, have a strong liking towards one parent – or have a strong dislike toward a stepparent – do their objections have any weight in court rulings in deciding child custody? Or is it all based on income, possessions, all calculative?

It all depends on their age, the judge in the case will consider any input and place credence on the persons desire depending on their age a maturity.}{
