Trying to obtain conservatorship for my disabled children. How much estimated cost am I looking at?

Attorney fees vary. You're probably looking in the range of $2500-3500. There is also a court fee of $435, but many parents of disabled children are able to get that waived. I know that probably sounds like a lot, but it's actually a fairly complex procedure, requiring a minimum of one physical court appearance. You mention "children". It's likely that an attorney might give you a bundled price if more than one conservatorship is done at the same time. Also, some of us offer monthly payments, which could also help.
