We know well that money plays a role in divorce. Many studies have looked at financial stress in marriages and how it can lead to the end of those marriages.
Your spouse has to pay you alimony after the divorce. You assumed that meant monthly payments. It can, but your spouse is asking to pay you a lump sum instead and be done with it.
When dividing property during divorce, your household income becomes very important. To start with, you must fully understand what assets you control in order to divide them fairly. On top of that, you need to budget for your post-divorce life, and that starts with an understanding of what your income will look like after the split.
Imagine you and your spouse are in your 50s. You've saved up a nest-egg to pay for your retirement years. However, your spouse develops Alzheimer's disease, which means that you and your spouse are going to endure massive medical bills. Those bills could result in the exhaustion of all your retirement. Essentially, you and your spouse will have to wait until you're impoverished before Medicaid kicks in to help with the bills. One solution to this dilemma could be divorce.
