Dale became a county in Alabama in 1824, and it's located down in the south-eastern corner of the state. Many vital records were kept at that time though a complete county-wide registration of births and deaths didn't take place until at least 1908 when the state made it a requirement. So many Dale County public records are incomplete until 1908 or a bit later when all areas started to comply consistently.
You can make a request for Dale County public records either by mail at the main Vital Records office in Montgomery, or just visit the health department office in Ozark. There, you can just go to the counter with your request forms and have them in a few minutes. A mailed request can take a week or two. The forms and fees are the same in either case.
A search fee is part of the application, and it is not refunded if the records you want can't be found. So it's important to be as accurate as possible when providing the information on the forms.
Dale County Birth Records
You can only make requests for your own Dale County birth record, or for someone in your immediate family unless the record you want is more than 125 years old. That's when the privacy restrictions run out and the material becomes public domain. You may be able to find what you need for free at the library or State Archives at that point, but otherwise, it will cost $15 per record you have searched.
Dale County Death Records
Death records also carry a privacy restriction on their access, but this time it is only for 25 years rather than 125. So after 25 years, you can get a certified copy of anyone's Dale County death record. Until that time, you will be limited to immediate family members (children, parents, siblings, spouse). Much of this material is also available through the library or archive system since it is public domain. Older records (prior to 1908) will be very sparse and have only name, age and date of death.
Dale County Marriage Records
The state started recording marriages in 1936 though the Probate courts in each county have been doing so for decades longer. You can either make your request through the courthouse in Ozark or the health department, depending on the age of the records. There are no restrictions at all so you can get copies of any Dale County marriage records you wish. The health department will charge $15 per record but the courthouse may have a lower fee.
Dale County Criminal Records
The only Dale County criminal records you are going to be able to request are your own due to their confidential nature. Certain types of employers are also permitted access so they can do background checks when hiring. The county doesn't hold these records, so you will have to send your application forms to the Alabama Criminal Justice Information Center in Montgomery. The forms will require your fingerprints, and the cost for a record retrieval is $25 USD.
