There are times when the divorce process is necessarily long. Some couples have complicated estates that must be divided carefully. Child custody proceedings can also be lengthy.
But a significant number of divorces take longer than they need to simply because couples have unresolved anger and grief toward one another. Even if the divorce details are simple and straightforward, some couples will engage in lengthy and expensive legal battles over easily replaceable property, or will raise other disagreements which are more punitive than practical. This ends up hurting both spouses by making the divorce far more expensive and acrimonious than it needs to be.
