This social stigma was incorporated in law: the Registration (Scotland) Act 1854 [Link] required that all illegitimate births be marked as such in the original register (a requirement which wasn’t removed until 1919). Section 35 of the Registration (Scotland) Act stated:
In the Case of an illegitimate Child it shall not be lawful for the Registrar to enter the Name of any Person as the Father of such Child, unless at the joint Request of the Mother and of the Person acknowledging himself to be the Father of such Child, and who shall in such Case sign the Register as Informant along with the Mother
Provided always, that when the Paternity of any illegitimate Child has been found by Decree of any competent Court, the Clerk of Court shall, within Ten Days after the Date of such Decree, send by Post to the Registrar of the Parish in which the Father is or was last domiciled, or in which the Birth shall have been registered, Notice of the Import of such Decree in the Form of the Schedule (F.) to this Act annexed, or to the like Effect, under a Penalty not exceeding Forty Shillings in case of Failure; and on Receipt of such Notice the Registrar shall add to the Entry of the Birth of such Child in the Register the Name of the Father and the Word "Illegitimate," and shall make upon the Margin of the Register opposite to such Entry a Note of such Decree and of the Import thereof
Section 36 of the Registration (Scotland) Act also illustrates an unusual feature of Scots law which distinguishes it from English law:
In the event of any Child, registered as illegitimate, being legitimated per subsequens matrimonium, the Registrar of the Parish in which the Birth of such illegitimate Child was registered shall, upon Production of an Extract of the Entry of such Marriage in the Register of Marriages, note on the Margin of the Register opposite to the Entry of the Birth the Legitimation of such Child per subsequens matrimonium, and the Date of the Registration of such Marriage
From a genealogy perspective, the main import of illegitimacy is that it can prove a significant obstacle to tracing the child’s paternal ancestry. However, it need not always prove to be a brick wall.
Take the case of George Kerr Waterston, an illegitimate child born on October 9 1863 in Dunnichen, Angus. His statutory birth record does not name his father, instead just giving his mother’s name as Elspeth Waterston. As mentioned earlier, the law stated that in cases of illegitimate children, the father’s name could only be included if the father signed the register in person. The following entries from the records of Dunnichen parish demonstrate that the strict rules in force for civil registration did not apply to the Church, and thus how Kirk Session records can often be used to identify fathers of illegitimate children.
At Dunnichen the 18th day of October 1863 years
[…]

At Dunnichen the 6th day of December 1863 years
[…]
Compeared Elizabeth Waterstone, and the Moderator having produced the following letter from John Kerr Greenhillock
Greenhillock 23 [November?] 1863
Sir,
I have not come as you hopped but I hope you will Baptise the child.
(signed) John Kerr
Your Servant
The Session hold that it was a sufficient acknowledgement by the said John Kerr.
The said Elizabeth Waterstone being suitably admonished by the Moderator was restored to the privileges of the Church.
