An uncontested divorce is the most desirable route, but sometimes, it's impossible. It is in everyone's best interests to keep things as amicable as possible, although it might not seem like that at the time.
Divorce by mutual agreement is designed to promote a culture of cooperation, so even if there is disagreement over ancillary matters, it can be minimised.
To conclude, an uncontested divorce is the gold standard amongst family lawyers and the judiciary. Uncontested divorce has the least mental and psychological fallout and is usually quicker and less costly.
However, sometimes a contested divorce is unavoidable, which is why professional legal advice is so important. Every good divorce lawyer knows that compromise is the only way forward and will seek to minimise points of contention while protecting their client's best interests.
