First: look at the document itself
Most administrative acts contain a line stating to whom and within what period they can be appealed. People skip it, because they only read the bad news at the top.
If that line is missing or wrong, that is itself a circumstance in your favour.
Bring the envelope or the receipt too. The date of receipt, not the date of issue, usually determines when the period starts.
Silent refusal
If you filed an application and the authority does not reply within the statutory period, silence is in certain cases treated as a refusal and can be appealed.
Many people wait for months because nobody told them that the absence of a reply is also a decision that can be challenged.
Two routes
Administrative, before the superior authority. Faster and usually free or cheap. Not always mandatory, but sometimes it is.
Judicial, before the administrative court.
Which one is yours depends on the type of act. Setting off down the wrong one costs you the deadline, which is the most expensive mistake here.
What gets examined
Competence: was it issued by the authority entitled to issue it. Form: does it contain the required elements and reasons. Procedure: was the process followed, were you heard, was the evidence gathered. And only last, the substance.
A significant share of these acts fall on procedure rather than because the facts were different.
Enforcement does not always stop
An appeal does not by itself always suspend the act. Sometimes suspension has to be requested separately, and that is assessed at the start rather than once enforcement has begun.

What I will need
The act itself, in full, including the reverse side. The envelope or receipt. Everything you filed beforehand. If you have missed a deadline, say so immediately, because even that sometimes has a way out.
