El testamento queda en la notaría.

Here queda comes from quedar and means something like remains, is left, or stays.

In El testamento queda en la notaría, the idea is that the will is left at or kept at the notary’s office. It is not just about location; it also suggests that this is where it stays.

Both can talk about location, but they are not exactly the same.

• Está en la notaría = it is in the notary’s office
• Queda en la notaría = it remains / is left / stays in the notary’s office

So quedar adds the idea of something being left there or kept there, not just physically located there at one moment.

In a legal or formal context, queda sounds very natural because it suggests the document stays deposited there.

Queda is the third-person singular present tense of quedar.

So the pattern is:

• yo quedo
• tú quedas
• él / ella / usted queda

Since el testamento is singular, the verb is queda.

Notaría means notary’s office or notarial office, not the person.

So:

• notario / notaria = the notary
• notaría = the office or practice of the notary

In this sentence, la notaría is the place where the will is kept.

En la notaría focuses on the place: the will is at the notary’s office.

Con el notario would focus more on the person: the will is with the notary.

Both can make sense in some situations, but they are not identical:

• El testamento queda en la notaría = the will remains at the office
• El testamento está con el notario = the will is with the notary

The original sentence is specifically about where the document is kept.

Spanish often uses definite articles where English may or may not use them.

• el testamento = the will
• la notaría = the notary’s office

In this sentence, both are treated as specific:

• a particular will
• a particular notary’s office

That is why the definite articles are used.

Yes. The written accent tells you that the stress falls on -rí-:

no-ta-RÍ-a

Without the accent mark, you would expect a different stress pattern, so the accent is important both for spelling and pronunciation.

Yes, that is grammatically correct.

But the nuance is slightly different:

• está en la notaría = it is in the notary’s office
• queda en la notaría = it remains / is kept in the notary’s office

So está is more neutral and just states location.
Queda sounds a bit more precise if you want to express that the will is left there as its proper place.

It sounds fairly formal or administrative, mainly because of the words testamento and notaría, and also because quedar is being used in a slightly formal, document-related way.

It is still perfectly natural Spanish, but it fits especially well in legal, official, or explanatory contexts.

No. Quedar is a very flexible verb in Spanish. Depending on the context, it can mean things like:

• to stay / remain
• to be left
• to be located
• to arrange to meet
• to fit / suit

In this sentence, the relevant meaning is to remain or to be left somewhere.

That is why context is very important with quedar.
