There are several different databases that you can use to search for public records filed in particular counties.
There is texaslandrecords.com although Loving County records aren't accessible which is a shame because it is a really well put together and very efficient.
Courthousedirect.com is another resource. However, unless you are doing a lot of searches then I wouldn't go that direction.
Countyrecords.com is fantastic and I find it extremely thorough and helpful. I'm will have to check but I believe that if you purchase a subscription to a certain county then you can preview for $2.00 and purchase for $4.00 (no matter if it is 4 pages or 50). However, this again is all in relation to the quantity and depth of your search.
My personal opinion and that which I use the most is undoubtedly texasfile.com . You create an account and add funds in increments of $20, $50, $100, $250, etc. There are 4 major reasons I prefer texasfile.com:
1) Counties - You can pretty much access any county in Texas and some out of state counties. The dates for each specific county can range from 100 years back to 20-30 or less. I think the reason for this is if a county is located in an active area such as the Permian then the date range will correspond with the demand.
For example, Loving County date range for searching is 5/09/1905 to 4/28/2017.
2) Pricing - I really like how they provide the Preview option for $2.00. Maybe I'm just cheap but the Preview option allows you to in essence preview a document and more importantly make sure that it is the document that you are looking for. Let's say I had a Assignment & Bill of Sale to look up or a Probate. I can preview for $2.00 instead of $15 or $20+ dollars and be certain of whether or not I've got the right document. Only drawback is that if you preview and find the doc you are looking for? You have to pay the $2.00 then a $1.00 per page. My rule is if it is 5 pages or less then I buy instead of preview.
3) Ability to search by Legal Description - Besides grantor/grantee, doc number, and Vol./Page, you have the ability to search by legal descriptions. Whether it be the Section, Blk, Abstract, Survey, etc. you have that resource at your hand and it is rather straightforward.
4) Search Statewide - For $5.00, you can search all records in any and all counties in Texas. I love this. Log on to your account, from the home page click "Search Records" and at the top of that page above where all the Texas counties are listed, you can do a statewide search. I've found that my great grandmother owned interest in counties my family never even knew about. I've found documents that make reference to one county that for whatever reason was not filed in that county, only to find that it was filed in a neighboring county or a county where that person was domiciled.
One thing to keep in mind, if you do a statewide search for "Smith" then your results will be substantial. If you searched "Sriracha" as a last name, then your results will be limited and you can use the filter tool at the top to search for particular names. So if you are searching for "Smith" and you know the name is John Smith then search "Smith J*" which should limit your searches.
That's just my 2 cents. Other may advise differently, but searching is free, preview is nice, and you have access to several counties. Also beware or mindful, if you search "Newcombe" then search "Newcomb" as well. I always double-check if there could be a variation in names.
If you would like send me a friend request and just basically what you are looking to find, I can do some quick searches and provide you with the Doc # and Vol., Page. Then you can plug those numbers in and pull the documents.
Also! JOIN NARO haha. Great resource. I need to renew my membership.
