How long do you have to appeal after sentencing

As stated it is 30 days from sentencing. Since you pled quilty it will be very difficult to appeal this.

Do I need to disclose minor tickets every time I am asked about arrest record and also can I somehow seal(?) it?

These sound like violations rather than crimes. They do not have to be mentioned. They should not show on a criminal record except as violations.

I was charged w/ a felony in NY under PL 215.50 (3), specifically Intentional disobedience or resistance to the lawful process.

I'm assuming that the attorney you fired was your family law attorney. At this point you need a criminal defense attorney and this is who you...

It does not sound like the police were involved so there would be no court fine. These stores send out their own civil demands, but rarely follow...

Is there a difference if you have a warrant and they have a holding on it

He needs to talk to an attorney on this one and perhaps the attorney can get the second warrant taken care of.

If a person is sentenced to a dwi program in the jail system does the prisoner have to pay for the program

His best place to ask this question is at the place he is incarcerated. I agree that it is unlikely he would have to pay.

When a lawyer is arrested for possession of marihuana in New York, does he have to report that to the NY Bar?

I agree, the rule is only in the event of the conviction of a crime. As we all know and arrest does not necessarily mean a crime was committed.

I plead guilty to a violation of section §1-05 (I) of the NYC Park Rules for "biking in park" - do I now have a criminal record?

I think it would all depend on whether it was a violation that you pleaded guilty to. A violation does not show up on your record.

How long does it take before a conviction of a illegal possession of a firearm is eligible to be expunged?

New York does not allow expungement of any crimes.

You would need to present some evidence of the truth.
