Some but not all Legal Services agencies in California handle custody cases. You will need to qualify as low-income; this is usually a percentage of the federal poverty level, and the agencies will determine your eligibility. The related link has links to the California agencies, statewide first and then by county. Look for links to "legal services", "legal aid", "legal assistance", volunteer lawyers", or similar wording.
A father who is struggling with a child custody case may be able to find pro bono legal help, which means a regular lawyer will handle the case at no charge. Call the California State Bar and ask them if they have any local recommendations.
Lawyers who take cases pro bono usually do so because they believe in the case and will handle it for free because it contributes to the "public good" (pro bono is short for the Latin pro bono publico - "for the public good"). These are usually cases for which the lawyer expects no payment. A wrongful death case, on the other hand, is the type of case for which lawyers do expect payment, because a verdict for the plaintiff usually means the defendant must pay money damages, and the lawyer will take a percentage of that. Most lawyers who handle wrongful death cases will do so without charging a fee up front - so if what you mean by "pro bono" is a lawyer who will take your case without asking for a retainer, then any wrongful death lawyer fits the bill (of course the lawyer has to believe the case is winnable). Then if you win, they lawyer takes a cut of the damage award; if you lose, you probably won't owe the lawyer a fee, although you may have to pay some expenses. The easiest way to find a lawyer is through a lawyer-referral service, and there are many in California.

You can find a pro Bono lawyer for civil and criminal case combined in Otero county New Mexico at White Sands Rotary Club.
Some private lawyers may take an occasional pro bono case if it interests them, but it's very rare - especially for custody cases - and they don't advertise. If your income is low enough to qualify, you may be able to get free legal help from Legal Aid. A directory of their local offices is the first related link below. Not every local office will handle a custody case, depending on their case load; you'll have to call and ask. I found this at the second related link, which has links to additional Virginia legal services by region and county.
Laws can vary from state to state and by case to case. A mother can get custody if she is on depression medication, but it is best to seek the advise of a lawyer.
The best way to get sample character reference letters for a child custody case is to ask the lawyer handling the case. You can also call a family court lawyer and ask them to mail you samples.
One can use a custody lawyer for many reasons but the most prominent one is when one is fighting a case about a child. You can always go to your local court and seek information on current custody lawyers.
"Pro Bono" is short for "pro bono publico", which means "for the public good". It is usually used to describe a lawyer who takes a case for free - so the typical lawyer's fee on a pro bono case is $0. Some lawyers will take a case at a reduced rate (technically, that's not "pro bono") but lawyers fees vary a lot depending on location and type of case, so there is no "typical" lawyer's fee in Tennessee. Most lawyers who do not charge a fee are actually employed by a Legal Aid or Legal Services office (for civil cases), or are assigned counsel under the Indigent Defense Program or work for a Public Defender office (for criminal and some family cases). Links to these offices are at the related link below.
No unless a law firm decides to give you a pro bono lawer which is highly unlikely
It's up to the lawyer if he wants to take your case for free.
Look in yellow pages under"legal aid offices". A lawyer may choose to take on a case pro bono though this is totally at the discretion of the lawyer.
