The legal system puts an incredible burden on behavior at the beginning of one of the hardest things you'll go through in your life. Your children, finances, and property are at risk. But you're still expected to make rational decisions. The first few months of divorce proceedings are imperative for you to rely on your lawyer's advice.
If you are planning on going through a divorce, and you have children, do not discount couples counseling during a divorce. You're still going to have to co-parent and won't be able to do that well without good communication.
Limit Contact with Your Ex
Consult your lawyer before hauling off and acting emotionally. Again, this is one of the hardest things you'll ever have to go through, but avoiding unfriendly contract with your ex is imperative. For example, some lawyers will place restrictions on their clients if contact with their ex is consistently spiteful. It is not uncommon for divorce lawyers to restrict these clients by not allowing texts to be sent to the ex without first being approved by the lawyer. Fighting with your ex will only get you into trouble with the divorce judge, avoid it at all costs.
Tell Your Lawyer Everything
Be transparent with your lawyer, and definitely do not lie. Your lawyer has the power to fire you if they discover you've been dishonest. You will not gain anything from lying, you will only lose. Be up-front with your short-term, mid-term, and long-term goals. They may be legally unrealistic, and your lawyer will tell you if they are. For example, in some circumstances, it is unrealistic of a client to refuse to get a job because they think they can live off alimony.
Your Lawyer Usually Knows Best
Accept the reality that your lawyer presents to you, they know how the law works. There are probably going to be some hard truths you will have to swallow. But ultimately, remember that your lawyer is on your team, and you should do whatever you can to help your lawyer win for you.
