Regarding thesis supervision, students will be subject to the regulations established in the Royal Decree 99/2011, of 28 January, which regulates official doctoral studies.

The Doctoral Studies Regulations, approved by the Governing Council of the Universitat de València ACGUV 206/2017, of 25 July, modified by ACGUV/2018, of 10 July, establishes with regard to the supervision of theses:

Article 3. The Academic Committee of the Doctoral Programme

1. The Academic Committee of the Doctoral Programme is responsible for the programming, coordination and academic and teaching supervision of the activities of the programme.

4. The Academic Committee of the Programme has the following competences:

a) To propose to the Doctoral School the list of possible PhD students for the supervision of doctoral theses, as well as the research lines offered.

b) To propose the admission to the doctoral programme.

c) To assign to each PhD student the supervisor(s) and advisor(s) of the doctoral thesis, as well as to approve their modification in a reasoned manner.

d) To make public the procedures they consider appropriate in order to guarantee the quality of doctoral theses, both in their preparation and in the assessment process, before they are deposited.

e) Annually evaluate the personalised activities document and the PhD student's research plan.

f) For the purpose of awarding the international mention in the Doctoral Degree, to authorise the stay and activities carried out in another State, either in a higher education institution or in a research institution.

g) All other competences necessary for the proper performance of their duties.

Article 4. Doctoral Thesis Advisors

1. Once admitted and enrolled in the doctoral programme, all PhD students shall be assigned, within a period of three months, an advisor by the corresponding Academic Committee, who shall be a doctor with accredited research experience, linked to the unit or school organising the programme.

2. The advisor shall be responsible for ensuring the interaction of the PhD student with the Academic Committee and, in particular:

a) to ensure that the training and research activity of the PhD student is in line with the programme;

b) to guide the student in the choice of courses, seminars or other non-regulated activities aimed at research training.

Article 5. Supervision of Doctoral Theses

1. The Academic Committee responsible for the programme shall assign each PhD student, within a maximum period of three months from enrolment, a supervisor for the doctoral thesis, who may or may not coincide with the person designated as advisor. This assignment may fall on any doctor with duly accredited research experience, regardless of the university, centre or institution in which they provide their services. A doctoral thesis may be co-supervised by a maximum of three doctors.

2. No doctor of the Universitat de València may supervise or co-supervise more than 10 doctoral theses at the same time.

3.  The supervisor may resign from the student's supervisory duties by means of a reasoned resignation letter presented to the Academic Committee of the Doctoral Programme, which, if appropriate, will resolve the request and proceed to the appointment of another supervisor so that the student can continue the doctoral programme.

4. The Academic Committee may modify the appointment of the doctoral thesis supervisor at any time during the completion of the thesis, after hearing the PhD students and the supervisor(s), and provided that there are justified reasons.

5.  The general regulations of the Universitat de València that regulate the activity of the teaching staff will establish the equivalence in credits of the supervision of doctoral theses.

Likewise, article 9 establishes that the Universitat de València may reach agreements with foreign universities to develop doctoral theses under a joint supervision system. In this case, PhD students will carry out their thesis work under the control and responsibility of at least one thesis supervisor from each of the universities signing the agreement.

The Universitat de València has a "Doctoral Commitment Document" approved by the Doctoral Subcommittee on 17 October 2011, which defines the respective rights and responsibilities and the reciprocal commitments of the signatory members in order to ensure the achievement of the objectives defined in the Programme during the period of preparation of the doctoral thesis. In summary, this document includes:

- Responsibilities and commitment of the thesis supervisor: commitment to regularity, motivation of self-reliant initiatives, original and innovative nature of the project and coherent with the research line.

- Responsibilities and commitment of the PhD student: To report the supervisor regularly on the progress of the project and its results, and commitment to follow any observations made by the supervisor.

- Confidentiality with the data and information that may be provided and commitment to use the information for the corresponding purposes, Intellectual Property Regime, recognising the PhD student the intellectual or industrial property rights that correspond to them in accordance with the current legislation.
