My husband is incarcerated nd we've been separated since 2010 . I want a divorce it's time and I heard he can proceed with these actions for only 1$ . Is this so and how can I help it along from outside

We are not familiar with a legal filing costing $1, maybe it's true but it doesn't seem like you would get much help for one dollar. My advice would be to investigate the process in your county. You might be able to do this pro se (represent yourself), Google the information and write up the motion yourself. That would cost less than one dollar (although there is probably a fee to file with the county).
