Five claims in circulation, and what the consolidated text says instead.
"The reform takes effect on 3 August 2026."
Commencement moved to 1 October 2026. DL 155-B/2026 gave new wording to DL 108/2026's own commencement provision.DL 155-B/2026, de 31 de julho · DR n.º 147/2026, 5th Supplement, Series I
"The título declaration becomes mandatory from 1 September 2026."
No 1 September date appears anywhere in this diploma. The declaration commences 1 October, with the rest of it. A separate rule does start on 1 September: the flat 7.5% non-resident IMT rate.RJUE art. 4.º-A n.º 14 · Decreto-Lei n.º 97/2026 for the IMT rate
"DL 108/2026 transferred verification risk to buyers."
DL 10/2024 removed the use licence from the documents required at the deed, effective 1 January 2024. DL 108/2026 adds a disclosure duty back.Decreto-Lei n.º 10/2024, de 8 de janeiro
"A property can be annulled for lacking an urban-planning title."
Voidability attaches to omitting the statement. Declaring that no title exists is one of the three permitted positions, and the sale stays lawful.RJUE art. 4.º-A n.º 14, alínea c)
"The municipality now has only one year to challenge a title."

The government's original proposal did set one year for the issuing body. The enabling law, Lei n.º 9-B/2026, then set a floor below which the Ministério Público's period could not fall, so the enacted text could not land shorter than three years. Summaries written at proposal stage and never revised still carry the earlier figures.
