Is Partus sequitur ventrem actually a Roman legal doctrine?

I have a question about Roman law.

Is Partus sequitur ventrem a (classical) Roman civil law doctrine?

  • If it is, what period was it formalised in?
  • Does it exist in practice before the Corpus Juris Civilis?
  • Is there a tension between this doctrine and the rights afforded under the patriarchical system of Roman society?

Thanks in advance.

No idea. However, here is a book you may want to look into:

Encyclopedic Dictionary of Roman Law

The entries Fructus rei prignotatae and Partus ancillae mention children born into slavery under some conditions.

Gibbon talks about it somewhere. Here is an example from the Justinian code:

servi autem in dominium nostrum rediguntur aut iure civili aut gentium: iure civili, si quis se maior viginti annis ad pretium participandum venire passus est. iure gentium servi nostri sunt, qui ab hostibus capiuntur aut qui ex ancillis nostris nascuntur.
