Interesting stat is how many can't be completed. Ticos are excellent at running and hiding from the police that look to serve the papers or enforce court orders.
Know from personal experience, many of these Ticas don't want the father on the birth certificate at birth (or aren't real sure who to name). This law allows them a second chance to name the father and it isn't final 'till the DNA comes back. But it allows them to begin getting Ch*ld support when they want too or need to to force the father to take some responsibility. That is, IF they can find the right guy.
Even more interesting is the enforcement.
IF the police find the deadbeat, they serve papers. Then if he falls behind on the ordered payments, the police begin to look for them.
IF they find them, then they have a chance to pay and if not, off to jail they go until someone comes up with the cash.
Have one Tico friend who does the 'hide-out' routine pretty often when he's falling short. Course with 5 K*ds and never married, he's in a tough boat but he climbed in there himself. Spent time in jail until mom just couldn't take it anymore...
