You would not need a lawyer to dissolve a marriage, but you would need to deal with the legal system. In fact, you could represent yourself in almost any legal proceeding in Missouri. Whether this could be a good idea would depend on your unique circumstances. Generally speaking, it is a good idea to get legal advice if you have any disagreements with your spouse — or if there is any indication there could be a disagreement in the future.
Despite the efforts of the courts and the legislature to simplify the process, divorce is still relatively complicated. The Missouri courts have some information online — you can find most of it at their family law self-help center. “Self” is the operative term here. Court officials and staff do not advise on individual cases.
If you were to organize your own divorce, you would want to start with the sections on the dissolution of marriage. You will need to gather various financial data, family information and so on, and then enter all of this into the appropriate documents. After your paperwork is complete, you would file it with the appropriate authorities and follow court procedure as indicated.
Although the process is far from simple, most of it is laid out clearly in publicly available resources. The main issue with all of this that divorce is not all about paperwork and procedure.
It is unfortunate, but, with everything at stake in a divorce — the future of your family, your finances and the distribution of your assets — sometimes disagreements seem to appear out of thin air. Even if you are able to perform all of the official procedures perfectly, you may still want to retain an advisor to make sure you are securing the best possible future for your family. Please do not think of this as legal advice. It is only meant as information.
